Concatenated Forward Error Correction with KP4 and Single Parity Check Codes
Diego Lentner, Emna Ben Yacoub, Stefano Calabrò +3
Concatenated forward error correction is studied using an outer KP4 Reed-Solomon code with hard-decision decoding and inner single parity check (SPC) codes with Chase/Wagner soft-d…
Experimental Comparison of PAM-8 Probabilistic Shaping with Different Gaussian Orders at 200 Gb/s Net Rate in IM/DD System with O-Band TOSA
Md Sabbir-Bin Hossain, Georg Böcherer, Youxi Lin +10
For 200Gb/s net rates, cap probabilistic shaped PAM-8 with different Gaussian orders are experimentally compared against uniform PAM-8. In back-to-back and 5km measurements, cap-sh…
Nonlinear Equalization for Optical Communications Based on Entropy-Regularized Mean Square Error
Francesca Diedolo, Georg Böcherer, Maximilian Schädler +1
An entropy-regularized mean square error (MSE-X) cost function is proposed for nonlinear equalization of short-reach optical channels. For a coherent optical transmission experimen…
Spiking Neural Network Equalization on Neuromorphic Hardware for IM/DD Optical Communication
Elias Arnold, Georg Böcherer, Eric Müller +4
A spiking neural network (SNN) non-linear equalizer model is implemented on the mixed-signal neuromorphic hardware system BrainScaleS-2 and evaluated for an IM/DD link. The BER 2e-…
Spiking Neural Network Equalization for IM/DD Optical Communication
Elias Arnold, Georg Böcherer, Eric Müller +4
A spiking neural network (SNN) equalizer model suitable for electronic neuromorphic hardware is designed for an IM/DD link. The SNN achieves the same bit-error-rate as an artificia…
Experimental Comparison of Cap and Cup Probabilistically Shaped PAM for O-Band IM/DD Transmission System
Md Sabbir-Bin Hossain, Georg Boecherer, Talha Rahman +9
For 200Gbit/s net rates, uniform PAM-4, 6 and 8 are experimentally compared against probabilistic shaped PAM-8 cap and cup variants. In back-to-back and 20km measurements, cap shap…
Comparison of PAM-6 Modulations for Short-Reach Fiber-Optic Links with Intensity Modulation and Direct Detection
Tobias Prinz, Thomas Wiegart, Daniel Plabst +6
PAM-6 transmission is considered for short-reach fiber-optic links with intensity modulation and direct detection. Experiments show that probabilistically-shaped PAM-6 and a framed…
Experiments on Bipolar Transmission with Direct Detection
Thomas Wiegart, Daniel Plabst, Tobias Prinz +6
Achievable information rates of bipolar 4- and 8-ary constellations are experimentally compared to those of intensity modulation (IM) when using an oversampled direct detection rec…
